RESILIENT HEEL-PAD.

specification of Letters Patent. Patented Sept if?, liceit Application filed May 24, 1917. Serial No. 170,586.

My invention relates to resilient heel-pads` lor top-lifts for shoes, and is an improvement on the ordinary types, now in use.

Iniitting resilient heel pads or top lifts to worn shoe heels, lifts of leather, or similar material, of equal thickness with that of the resilient heel pad are usually removed.

Hitherto it has been diiiicult to obtain a neat and finished junction line between the leather lift and the resilient heelpad, with` out the laborious and expensive method of cementing the two surfaces to each other, in addition to the nailing of the one to the other.

Moreover, the use of compressed paper for the inner lifts of leather, has tended to increase the ragged or uneven character of the perimeter of the heel after worn lifts are torn away, and one of the purposes ofv my invention is to provide for a neat and finished junction or -union between the shoe heel and resilient top lift to be applied to the heel.

Heretofore it has been attempted to provide such defined condition in a heel by having the upper surface of the resilient heel slightly convex, but this requires the use of cement as well as a nailing. Still another method has been suggested, that of a heel having an upper surface made deeply concaved and with the lower surface convex. The objection to either of these methods .has been mainly that they require special and expensive equipment for their manufacture, in that molds are required of concave and convex formations to produce the same, while according to vmy invention the resilient heel is produced with the usual equipment in which flat bottom heels are manufactured, by simply substituting a rand plate, which is riveted to the upper plate of the mold for the one now employed, and without change of location of naillholes and countersunk washers, whereby a flat bottom heel can readily be produced, to closely follow an irregular bottom siiirface of the shoe heel, and without the requirement of cement to fasten the same to the shoe-heel.

According to my invention andas embracing the essential main feature thereof, the upper surface of the heel is arranged with a central boss, whose upper surface `is flat and of the same level as the outer edge of the heel or arranged slightly below the plane of the said edge. The surface of the resilient heel YWeen the centrally located boss and the heel perimeter is arranged with 'holes and countersunk washers located in4 the formation c the heel about midway between tlie edges of the boss and the perimeiter of the resilient heel, with the result that when such a. heel is applied to a shoe-heel and the nails are tightly driven down with a nail-set according to the usual cobbler7s practice, there is a reaction set up between the surface of the central boss and the edge of the shoe-heel to` cause the heel pad to tightly cling to the shoe heel, even though the surface ofthe shoe -heel. is of irregular contour oroutline, thus insuring a far more comfortable and symmetrical character of heel-pad.

The nature, scope and characteristic features of my inrei'ition as thus liereinbefore defined will be better understood from the accompanying drawings taken in connection with the following description thereof.

In the'drawiifigs1-- Figure l, is a side elevational view of a shoe, showing the shoe-heel with a resilient heel. pad in application thereto embodying the essential main features of my said in- 'vention.

Fig. 2, is an underneath plan view of the resilient heel'pad, showing the detailed. arrangement of the upper surface of the saine; and

Figs. 3 and 4 are respectively, transverse and longitudinal secticxal views on the lines ai, and y, y, of Fig. 2.

Referring to the drawings a, is the shoe and al the heel thereof. l

The resilient heel-pad is of the flat type, formed in the upper surface with a centrally arranged boss 1, preferably in shape or form conforming to that of tl' contour or outline of the heel pad b. as cir rij," illustrated in Fig. 2, and with a depression b2, bounding the, pad from the location of the l boss and. extending to the perimeter of the v a bounding depression, preferably with the ioo heel pad Z). The deepest portion of the depression being about the boss pand decreasing in depth gradually or otherwise, to the perimeter of the heel pad. The boss b1, arranged l 'about midway between the edges of the boss b1, and the heel-pad perimeter, as

clearly shown in Figs. 2 and 4, wherebyI when the resilient pad b, is applied to they shoe-heel a1, and nails are tightly driven 'down into the said heel with a nail-set, according to the cobblers practice isgestablished a reaction between the surface of the central boss b1, and edge of the shoe-heel al causing thereby the resilient heel-pad. to

tightly cling to the shoe-heel al, even though the surface of the shoe-heel is irregular or uneven, thus affording greater comfort to the wearer due tothe lessening of'strain on the heel-bone by-the cushioning eect induced therefrom. I v

Having thus described the :reliure andobn 5 jects of my mventlon, whatlciim as new and desire to secure by Letters Patent ist;-

A uni'tjresilient flat bottom heel pad havi i ing anfintegral boss' locatedbelow the plane of the edge and having a depression between the `boss and edge of a depth .of/gradually decreasing dimension from the boss to 'said' edge 'to thereby provide an edge clinging vheel pad, substantially as and for the purposes described. f
